Ruderal flora, as well as the vegetation that flora forms, represent an extremely dynamic floristic-vegetation complex and arean integral part of the most immediate living and working environment of human. It is formed and developed mainly in human settlements, as well as in the other anthropogenic environments that are occasionally or permanently under direct or indirect influence of various forms of human activity. Ruderal vegetation is found not only directly around the settlements, but also around all urban and accompanying facilities: along roads, paths and fences around houses, yards, walls and roofs, in avenues, on ruins, construction sites, landfills, along railway tracks, road and defense embankments, on wet and nitrified banks of rivers, near human settlements, in abandoned lawns, on the street walks with sandy areas, cemeteries, in degraded pastures, forests, etc. This essay presents the distribution and representation of economically harmful, invasive and quarantine weed species (Abutilon theophrasti, Agropyrumrepens, Amaranthusretroflexus, Calystegiasepium, Cirsiumarvense, Chenopodium album, Chenopodiumhybridum, Convolvulus arvensis, Cynodondactylon, Daturastramonium, Sonchusarvensis, Sorghum halepense, Xanthium strumarium…) at ten sites in the Nisava district. The assessment of species representation was done in two shootings (May and August) according to scale 1-4. The proper selection of herbicides depends, in a large extent, on the presence of dominant weed species and on the time of application.

A new concept of LNG FPSO based on a deep-draft semi-submersible hull is introduced. With the deep draft, small water plane area, low center of gravity and large radius of gyration, the new LNG FPSO offers very low motions. This low-motion LNG FPSO platform provides more options and flexibilities in the selection of LNG liquefaction units, LNG containment systems, construction sites, installation methods, mooring systems (i.e. no requirements for weather-vaning), riser system and less down time compared with a conventional FPSO hull. Global performance and sloshing analyses for the new LNG FPSO hull and the conventional FPSO hull are performed to compare their operating performance for West Africa and the Northwest Australia environments.

Liquefied Natural Gas (LNG) industry is among the fastest growing energy market sectors. The gas terminal in Klaipėda allows Lithuania to import natural gas from various countries around the world. One of the most debatable subjects is the location of the future terminal. The problem pertaining to selection of construction sites for the LNG terminal should be investigated and solved using the set of multiple conflicting criteria. Many researchers argue that similar problems should be solved by applying several different Multi-Criteria Decision-Making (MCDM) methods. The research presents the model for application of three different MCDM methods and aggregation of solution results for the problem, which is based both on different objective data and on investigation of expert opinions for determining subjective criteria weights for the problem.

Abstract Water management has become one of the major interests in arid and semi-arid regions. Scientists have suggested different criteria and methodologies for the identification of suitable dam sites. According to our literature review, we have used two major methodologies for the selection of suitable dam site location: geographic information system and remote sensing (GIS/RS) and multicriteria analysis (MCA) integrated with GIS/RS. The most common criteria used for the selection of suitable dam sites were slope, rainfall, land use land cover, soil type, lithology, lineament density, and hydrographic typology. All the factors were superimposed to prepare the synthesis map of water-harvesting structures, each thematic layer’s weight was determined, and storage water potential indices were calculated using water accumulation conditions. According to the water-harvesting location map, where the spatial distribution of the excellent (5%), very good (9%), and good (17%) aptitude classes is established in the northeast and central parts of the westward zone, the average located in the center of the zone. Study and weak are located south of the map; the area of moderate (25%) to poor (44%) suitability is situated in the south and southwest zone. The MCA was validated using an existing dam across the study area, where the MCA provides for the dam located in the good and moderate zones. The approach adopted in this study can be applied for any other location globally to identify potential dam-construction sites. From the point of view of the literature of multicriteria analyses of water recovery, areas unsuitable for surface water harvesting and dam projects are suitable for groundwater recharge.

The formwork made up of Industrialized Building System is being acknowledged in many writings as a construction method that has many advantages especially on aspects of construction sustainability. This paper discusses the outcome of a research aimed in determining factors and elements that lead to selection of responsive formwork system. A list of sustainability elements in construction development is being summarized through several references. The development of questionnaire survey took place whereby it has been divided by three parts that are the demographic of respondents, the selection factors of formwork system and responsive level of sustainability objectives towards formwork system. The survey was conducted in several construction sites in Malaysia. The findings highlighted the sustainability elements for optimal Industrialized Building System (IBS) formwork system. This study encourages application of modern method to response to sustainable construction.

Abstract Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.
